These new red, white and blue US forever postage stamps featuring military working dogs are designed to honor the nation's brave and loyal canines.
The sheet of 20 stamps features artist renderings of four breeds commonly used as military working dogs: German shepherd, Dutch shepherd, Labrador retriever and Belgian Malinois.
Each breed is pictured wearing a working harness, posing against a backdrop of a white star against a red or blue background.
The U.S. has used military working dogs alongside servicemembers since World War I for multiple purposes, including explosives and narcotics detection, search and rescue and security.
These forever postage stamps will always be equal in value to the current First Class 1-ounce letter mail price
